The ‘Iran Card’ in Russian Foreign Policy

Abstract Since the United States withdrew from the Iran nuclear deal in 2018, Tehran and Moscow have increased their collaboration. Iran supported Russia's war in Ukraine, believing that it would weaken the Americans, reduce the effects of sanctions, and benefit its battered economy. Similarly, Russia sought to use Iran as a tool to challenge US influence in the region. However, the authors contend, the costs and benefits have been asymmetrical: While Moscow has gained strategic advantages at minimal expense, the Islamic Republic has borne substantial geopolitical burdens. This study explores the evolution of Iran‐Russia relations and assesses the implications for both countries in their conflicts with the United States. It analyzes their cooperation on the wars in Syria and Ukraine, showing that Tehran has been compelled to act in Moscow's interests but has not always received the same support. This has come into sharp relief since the beginning of Israel's war on Gaza, as Iran has faced attacks on its allies and on its own territory. To defend itself and its interests, it needs advanced military equipment, which the Russians have yet to provide. The evidence indicates that Iran's reliance on Russia has led to more harm than benefit.
